fix: removed duped core types (#800)

A while back I added:

```json
    "paths": {
      "@openfeature/core": [ "./packages/shared/src" ]
    },      
```

To the tsconfigs, which helped with local dev by always resolving
`src/*` files from sibling packages instead of anything in their
`dist/`.

It also had the nasty side-effect of causing our type bundling to
include types from this package in it's output, causing duplicated
artifacts and possible compiler issues. I've overridden this with a
custom `tsconfig.rollup.json`.

Before this fix, the web/server SDK dists contained dupes of the stuff
in shared:

```ts
import EventEmitter from 'events';

type FlagValueType = 'boolean' | 'string' | 'number' | 'object';
type PrimitiveValue = null | boolean | string | number;
type JsonObject = {
    [key: string]: JsonValue;
};
type JsonArray = JsonValue[];
/**
 * Represents a JSON node value.
 */
```

After this fix, they import them:

```ts
import { BaseHook, HookHints, EvaluationDetails, JsonValue, EvaluationLifeCycle, ManageLogger, Eventing, ClientMetadata, ProviderStatus, ClientProviderEvents, GenericEventEmitter, CommonEventDetails, FlagValue, CommonProvider, EvaluationContext, Logger, ResolutionDetails, EventHandler, OpenFeatureCommonAPI, ManageContext } from '@openfeature/core';
export * from '@openfeature/core';
```
